Abstract

PURPOSE:To obtain the enclosed type engine necessitating no starter of large capacity and having no gas leak by a method wherein the starting device for the Stirling engine or the like is provided with a transferrer, feeding an operating gas from the large volume chamber of the small volume chamber of a gas sealing cylinder. CONSTITUTION:Upon starting, a heating pipe 4 and a heating wall 8 are heated by a burner heat source 9 and coolers 11, 14 are cooled, thereafter, the operation of the starter 26 is started upon a chance, in which a sufficient temperature difference is achieved. Upon beginning, a power piston 2 is being stopped at the lower dead point usually and when the starter 26 is energized after confirming it by a detecror 25, the driving of the transferrer 23 is initiated, the operating gas in a compression valve 19, having a large inner volume, is transferred to a back-pressure chamber 21 through a four-way switching valve 22 and the pressure in the compression chamber 19 becomes lower than the same in the back-pressure chamber 21. The piston 2 begins to move to the side of a displacer 3 by the pressure difference and when the transferrer 23 is stopped here, the operation of the engine is triggered by the initiation of the movement of the piston 2.

DETAILED DESCRIPTION OF THE INVENTION (a) Field of the Invention The present invention relates to an engine starting device for Stirling, Langin, Otto, Defeasel, etc. engines.

(1) Prior art The conventional technical means for starting an engine is to take out the engine body or drive shaft and start the engine with a starter.

(・→ Problems with conventional technology: Working gas tends to leak from the drive till extraction point in the engine body, and the starting capacity is usually about 600 W as a piston starting motor) Because it requires a starter, manufacturing It has the disadvantage of high cost and running costs.

(2) Purpose of the Invention To provide an engine starting device which is capable of producing an inexpensive and compact engine that prevents leakage of working gas and does not require a large starter as a starting motor. It is something to do.

(J → Key Points of the Invention A cylinder with a working gas divided by a slidable piston is provided, spanning one chamber and another. A bypass passage is provided in the bypass passage, and a A working gas is sent to the IU, which has a smaller internal volume than the larger chamber, and a JR transfer device is provided (for now, the transfer device is driven with a small input of 1. or several 10 W, of a closed structure type without gas leaks). It is possible to obtain an engine starting device that can reliably start the engine at once.

After passing through the tube (6), the inner tube (

The outer circle (support) shown by the chain line is the locus of the bottle of the connecting rod OI for the warp piston, and the inner circle (al is the locus of the bottle marked with 3 marks) of the connecting rod for the display/izer.

Next, we will explain and explain the operation of the Stirling engine. When starting up, the heating pipe (4) and heating pipe are heated using the burner heat source (9).
, (8) and the first cooler (tl) and the second
When the cooler (4) is cooled and a sufficient temperature difference is reached, the starter (26) is started. Note that at this start, the power screw (2) has stopped running at the bottom dead center, which is lower than the state shown in the diagram, due to the pressure of the enclosed working gas due to residual heat from the heating pipe (4) and heating wall (8). Detector for stop status with! 25), and the starter (2G) is activated, the transfer machine Q starts to drive, and the solid line (7 prefecture four-way switching valves (2) The working gas is sent into the back pressure chamber (21) and has a lower pressure than the B-compression chamber (relatively to the back pressure chamber 12+).

Due to this pressure difference, the power piston (2) starts to move toward the display 2 (3) 0111, that is, upwardly at t7, and at this point, when the transfer machine 03) is stopped, the power piston (2) starts moving. As a result, the Stirling engine is operated as described below.

Of course, even if the power piston (2) is stopped at the 1st dead center, the detector Q ()) will detect the changeover valve (2) as shown in the dashed line. Transfer machine (23)
, the working gas is moved from the large volume back pressure chamber (2I) to the small volume compression chamber 01, and the engine is started.

In addition, the detector I25) detects “C power piston (2)” l.
The T fat state is continuously sensed and the four-way switching valve (2) is alternately switched to change the direction of movement of the working gas by the transfer device (c) between the compressor chamber θ9 and the back pressure chamber (2). Engine starting can be effectively enhanced by forward and reverse rotation.

In addition, if a) is used as the transfer device 1123) in which the discharge and suction directions are rotated in forward and reverse directions, it is necessary to use a four-way switching valve (22). Even if the switching of the valve (2 forces) is controlled by a timer mechanism, it will not work. In this way, when the power piston (2) is moved to the upper row by the drive of the transfer machine (23+), it will be interlocked with the single rhombic mechanism and the display will be distributed! 1-(3) too” At 12, the language disblazer rises and reaches the 5th point, but isothermal compression begins.

41, low temperature gas moves to the expansion chamber (5) via the heat regenerator (10) and the heating vibrator (4). During this movement, the low-temperature working gas is endothermically heated to about 600°C by the heat release of the heat regenerator (10), which stores heat in the isovolume heat release process described later.
A so-called isovolumic heat dissipation effect is performed.

Next, the working gas in the expansion chamber (5) is heated and expanded by approximately 600°C (C) by heating from the burner heat source (9), and the gas output is determined by heating pipe (4), thermal amphigenator (lO), and cooler 01. ) (14), the power piston (2) is pushed down, and at the same time, the displacer (3) is interlocked with the monorhombic mechanism.
The temperature also follows and falls, and the isothermal expansion effect is performed.

Then, the power piston (2) continues to descend due to the inertial force, and the display valve (3) rises and the working gas in the expansion chamber (5) is compressed. Heating vibrator (4) and heat regenerator (10
) and cooler (ll+ (+4+).At this time, the working gas heated to about 600℃ gives its heat to the heat regenerator (1011), which lowers its temperature to about 200℃ and is discarded into history. The so-called isovolumic heat dissipation effect of cooling in the container (marked (I4)) cannot be performed.

By repeating such a cycle, one power generator is driven by the output taken out from the stepped crankshaft (37).

(g) Effects of the invention The device of the present invention is a Ninita Kunou IJ that is partitioned by a piston.
